@QRPPPSK31 Hi Jack, tnx fer QTC. You welcome. If you have to setup an R8 remember: Set up/dwn stub for 6-10-12-15 m (i had to increase with a new stub +20cm the stub for 15m). Set up/dwn the connection under the 20m trap coil for 17m, not so long but you can move some cm. 20m - you can' t do nothing, only mods lenght of coil trap. 30m - you can cut or change the connection between the two traps (i had to cut 10 cm of alluminium tube for 30m SWR) 40m - tune the last stub on top of R8.
@fasthandslow Just trying it since 08 July on all bands. Great antenna. If the location is open to the skyline you will not have any problems to work DX station. Have worked CX ZP PY in S.A., VK9H 40m in OC, JX EU. no problem very close, ST0 in AF, some trouble with VU direction because i have mountain, no prob with JA AS., caribean sea and so on. Runing an Icom IC-7700 with his output power ... 200 Watts, don' t use any amplifier. Stay tuned ... gl gdx 73 de IV3TMM.
Hello, I was facing problem with Cushcraft R9 on the 80 and 4om tuning. Hard to find proper point on the coil to place the tapping pin. I want to make 3.573 for the 80m and 7.074 on the 40m Loading coil. Meanwhile for another band I got better SWR. I was using RigExpert A55 Zoom. Dou have any advice or video for adjusting the taping?
, but probably this way will change the 17m swr, be careful In this case you have to open the coil trap, it’ s a bit difficult but not impossible, good luck HI For 30m is the same way but in this case you can cut or alonge the tube between the two coils trap. In my case i cut 10centimeter the tube between the two coils trap. I suggest you to check very well the lenght of all alluminium tubes then tune ONLY 20m.
@brubatt Le fascette a croce per gli occhielli dei controventi non sono isolate dai tubi in alluminio della R8 ... non interferiscono. L' importante è che gli occhielli del fili in teflon non tocchino i vari stub altrimenti andrebbero in corto con il tubo principale. Ciao 73 de IV3TMM.
A distanza di 6 anni.... raccontaci... Io avevo la R-9 purtroppo l'ho dovuta levare perchè non potendo mettere stralli oscillava parecchio e i vicini avevano paura, per il quieto vivere ho cambiato. A me ha regalato tante soddisfazioni
Ciao francesco, complimenti per l'eccellente tuning della R8, che spero di poter utilizzare anche con la mia antenna.Come ti dicevo prox volta che rientro da Mosca ci vediamo per chiarimenti.Ti ho inviato mia mail via SMS. A presto 73
While I'm no expert, I'm surprised you'd want a vertical, being so close to a hillside, unless that direction is not important. On the ground that looks like it would be a kid magnet. "Wow, lets go climb that pole."
Ciao Francesco, personalmente ho sempre preferito non controventare le antenne per farle curvare con il vento ed evitare che si spezzino, tu hai trovato vantaggi? Io a breve monterò la R9 73
Hello, Great video, hopefully the R8 will be my next antenna. I’m very impressed with the guy wire support frame at the base of the antenna. How is the R8 performing on dx and what radio do you use? 73 de M3MQR
After 20m swr is OK, then check again your swr on 30m and then tune 30m. Finally check again 40m swr and tune it. It ‘ s a long way but this is the ONLY RIGHT way to tune R8. I immagine that 6/10/12/15m swr is OK. Hope that you will tune your antenna. 73 de Francesco IV3TMM and tomorow on trip to Burundi operating as 9U3TMM for one week, stay tuned. Ciao.
Hi Murilo, first of all i thank you for watching my R8 movie then i can say you to tune your R8 antenna ... For 20m band there is no easy way to tune antenna because if: 1) your SWR down point is under 14.000 Mhz then it say that antenna is too long ! 2) your SWR down point is up 14.350 Mhz then it say that antenna is too short ! so to adjust antenna you have to: 1) cut internal coil trap 2) allonge internal coil trap or allone alluminium tube under 20m coil trap
Great video. Can you tell me about the guy wire base? IS this custom designed or is there a company or person who manufactures these? If not, are there drawings of the guy wire base design?
Nice work! Any chance you could share those drawings with me. I would appreciate it. email: wh6qv@aol.com Please put your call sign in the subject line.

Ciao Serafino, mi dispiace la R9 non l' ho mai provata. Ho visto e letto solamente il manuale. Francamente, gli 80m super caricati ... non mi sembrano il massimo. Per il resto mi sembra uguale alla R8. Ciao de IV3TMM Francesco.

You don't know how to use words? To bad. Still shots and loud techno music are not helpful.
